Development process

Forewind has now achieved development consent for an agreed target installed capacity of 4.8GW of offshore wind farm projects, with the second of two 2.4GW consents received in August 2015.

Back in 2010 however, when the Round 3 zones were announced, Forewind’s priority was to ensure that the work associated with meeting this objective was managed effectively, and that demands on stakeholders and the supply chain were distributed evenly. To that end Forewind chose to develop the zone sequentially in stages, known as tranches.

The Zone Appraisal and Planning (ZAP) process used both available information and the outcome of stakeholder consultations to identify the optimum location of these tranches offshore.  Tranche A was identified 2010, Tranche B was defined in 2011 and Tranche C in 2013.

Within each tranche, Forewind identified a number of project sites, each with a capacity of up to 1.2GW. 

The area of each tranche was defined larger than the footprint required for the individual projects to ensure that the location of those projects remained flexible throughout the data collection and stakeholder consultation phase. The identification of the individual projects within each tranche has taken into account stakeholder discussions and had due consideration to environmental and engineering factors.

The location of the cable routes and onshore infrastructure hinged on the grid connections agreed in negotiations with National Grid. As Forewind received these grid connection offers, the onshore ZAP process got underway. The aim of this was to identify the optimum route for the export cable from the offshore tranche/project to the onshore substation(s).

Four projects – from both Tranches A and B – were identified and taken forward via two separate development consent order applications. The remainder of the Dogger Bank Zone was returned to The Crown Estate for its future use and the zone itself dissolved.
